What makes a function a function?

1 answer:

6 0

In a relationship between two variables x and y, the data set is a function, if every element of the domain corresponds to exactly one element of the range

that means

one element of x corresponds to exactly one element of y

In any function, there is an input value (independent variable or x variable) and there is an output value (dependent variable or y variable)

What makes a function a function? ------> one element of the input (variable x) corresponds to exactly one element of the output (variable y)

. Joan has a prescription for 100 Theophylline capsules. Joan informs the pharmacist that she only has enough money to purchase

liubo4ka [24]

Answer:

Step-by-step explanation:

There are 100 capsules and she can only buy 1/4

Multiply 100 * 1/4

100 * 1/4 =

100/4

We can check by calculating how many she leaves at the store

100 * 3/4 =

300 /4 = 75

The ones she bought , plus the ones she left behind should be 100 capsules

25+ 75 = 100

100 = 100

Use the distance formula to determine the distance between (-8,10) and (-6,7)

hjlf

Answer:

Distance: $\sqrt{13}$ units

Step-by-step explanation:

The distance formula is $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ where:

$d$ is the distance between points $(x_1,y_1)$ and $(x_2,y_2)$
$(x_1,y_1)$ are the coordinates of the first point
$(x_2,y_2)$ are the coordinates of the second point

We are given that:

$(x_1,y_1)=(-8,10)$
$(x_2,y_2)=(-6,7)$

To determine the value of our distance, $d$ , we plug in our given information into the formula and solve for

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$d=\sqrt{(-6-(-8))^2+(7-10)^2}$

$d=\sqrt{(-6+8)^2+(-3)^2}$

$d=\sqrt{(2)^2+(-3)^2}$

$d=\sqrt{4+9}$

$d=\sqrt{13}$

Therefore, the distance between $(-8,10)$ and $(-6,7)$ is $\sqrt{13}$ units.

One way a parallelograhm and a rhombos are diffrent

AnnyKZ [126]

A parallelogram does not need to have all its sides equal. It just needs two pairs of equal opposite sides. A rhombus on the other hand, has to have all its four sides equal. A rhombus is actually a special form a parallelogram. So, a rhombus is always a parallelogram but a parallelogram is not always a rhombus.
